1. Sorting speed significantly increased for very large tables.2. Alphanumerical data sorted correctly now (v1.13 had a typo in code so it didn't work in some cases).3. Unique count for values in column is now consistent with total count when dealing with empty values (previously unique count sometimes counts empty value).4. pt-BR locale added (thanks to Babelzilla's maurojs10)

For Mac users, now the Ctrl key used in all shortcuts (including drag-n-drop row/column) is switched to Command key! So the shortcuts work now.

Also for Mac, now context menu is hidden if you do a TableTools2-specific shortcut containing right mouse click (like Command+Alt+RightClick to sort multi-column, it used to be that the context menu will show up and stay there after sorting. Now it's hidden).

Changed restart shortcut to Ctrl+Alt+R from Ctrl+Shift+R (Command+Alt+R on Mac), so that the default force-refresh shortcut (Ctrl+Shift+R) of Firefox is preserved.
